The night cougars are a lightweight dual eye/tube goggle system that are comfortable to wear and easy to use. Powered by two high-quality first-generation light intensifier tubes and using fast precision optics the Night Cougar has one of the clearest and brightest images available in a first-generation goggle. Combine all of the above with a built-in infrared illuminator that lets you see in total darkness and you will be on your way to exploring even the darkest of places.
